[BK7231N] Aubess Mini Smart Switch 16A (EZB-WBZS1H16N-A V1.0) not working and LED1 blinks with irregular pattern (off, dim, off, dim several times, then off, bright, then again off, dim several times).
Voltage on C8 is stable 3.3 V, voltage on C9 fluctuates around 4.5 V. I'm a noob, sorry if dumb questions will occur. What to check next?
AI: How are you powering the switch, and have you double-checked that the wiring is correct according to the manual?
Yes
AI: Have you tried any troubleshooting steps already, like resetting the device, changing the load, or re-flashing the firmware? If so, what happened?
It is hardware fault, not firmware. No load attached.
